How do they make money?

Randomly came to this club on a Thursday evening. Free admission so that was cool. The inside of the club is probably the best out of any club in KC. When I came in, there was 1 girl on stage and about 5-10 just sitting around talking to each other. I went to the bar and got something to drink before going to sit at the stage. The dancers aren't allowed to sit with customers at the bar so I thought I'd get some action stage side.

Wrong. No girl approached me or the other 3 customers there even though 2 of us tipped the girl on stage. I don't get how they make money there. I guess a bunch of them are new because 2 out of the 3 girls I saw on stage were really bad at it lol. The quality of dancer is good, worst was probably a 5 but I don't think any are experienced. They also never actually took anything off so...

After a while of doing nothing, I just left. Cant say it was a total waste of time and money because I didn't really use any money other than money for my drink and a couple dollars to the girl on stage. Don't know if I'll be back though.
